Ok, I realise my mistake now. :) Let the ribbing begin.

The saa7115 registers are affecting the input capture. I suppose that my
original questions still stand though. What is the device doing the mepg
decoding and to anoyone's knowledge is it capable of resizing  output on the
fly?

 Does anybody have a good handle on the layout of the pvr-350 board, I was
hoping for some insight from those more informed than I? I have been playing
with scaling of the mpeg video for output via /dev/video16 on the PVR-350.
If I use the 'ivtvctl -f' option to perform some scaling on the decoder I
would expect that the resizing operation would be taking place on the
decoding side right before the signal is output from the card but this is
not the case since the encoded mpeg stream that the *PC* receives is even
scaled.

It was my (obviously faulty) understanding that the saa7115 would be
handling the mpeg decoding side exclusively and therefore the video
inspected prior to /dev/video16 output would be unaffected. I have also run
the tests without using the "ivtvctl -f" call and instead using discrete
"ivtvctl -g" calls to affect only the saa7115 registers and it is the same
result.

a) Can somebody fill me in on the details of the architecture in that the
"decoder" register settings are changing the incoming "encoded" mpeg stream?
b) Does anybody know of a way to off load the resizing operation to *only*
on the decoding side so that I can still grab full 720x480 incoming frames
on the PC and output a scaled variant via /dev/video16?

I know that there is currently a big push to get new releases out but any
help would be appreciated. Thanks again.

Corey
